" ELF MF on the local fields potential (LFP)s were irreversible within investigated time frame. the relative wavelet energy (RWE) of 4–8 Hz frequency band was significantly increased after sine ELF MF (SnMF)/square ELF MF (SqMF) in comparison to the control value. the RWE of slower oscillations(1–2 Hz) was significantly decreased after the repeated exposures to either SnMF or SqMF. the SqMF induced decreasing of the faster waves in the range of 64–128 Hz."
